Hey, I'm very new to the coding scene, actually I only started today on the first thing that isn't auto hot key (woo me!)

I downloaded an outdated external source for a game called sea of thieves and updated all the offsets I could gather and changed some other things about like a few functions but nothing more than I needed to as a beginner to get it working, and it works great, there's just one problem, in a lot of light the esp has a strange border around it making it hard to read, like this:

But it looks fine when in a darker backdrop area like this:

I just wanted to know if there was a way I could get rid of this annoying border so i could enjoy the effort I put into fixing the source for me and a friend of mine who I'm working with.
